MINUTE-G LASS SIGNAL.

SPECIFICATION forming part of Letters Patent No. 366,265 dated July 12, 1887.

Application filed February 28, 1887. Serial No. 229,241.

To all whom, it may concern: I

Be it known that I, SAMUEL SMITH, of Lawrence, in the county of Essex, State of Massachusetts, have invented a certain new and useful Improvement in Minute-Glasses,

of which the following is a description sufficiently full, clear, and exact to enable any person skilled in the art or science to which said invention appertains to make and use IO the same, reference being had to the accom panying drawing,forming part of this specification, in which the figure is an isometrical perspective view of my improved glass.

My invention relates more especially to that class of minute-glasses which are employed by cooks in boiling eggs and for similar purposes; and it consists in a novel construction and arrangement of parts, as hereinafter more fully set-forth and claimed, the object being to produce a simpler and more effective device of this character than is now in ordinary use.

The nature and operation ofthe improvement will be readily understood by all conversant with such matters from the following explanation.

In the drawing, A represents the body or frame-work of the glass, and B the glass proper. The side pieces, m, and feet x of the body are integral, being composed of a single 0 piece of wire, the top being inclined backward at an angle of about thirty degreesto the sides, as shown. A coil is formed in each of the side pieces, as shown at o, and disposed between them above the feet 00 there is a horizontally-arranged brace or bar, d, on which a bell, G, is hung. wire crate, D, which is supported on horizontally-arranged journals t, resting in the coils 4). Projecting upwardly from the top 0 of the crate Dthere is an arm, b, carrying a hammer, k, and projecting horizontally from the bottom of said crate toward the front there is an arm, S, carrying at its outer end a plate, 3 on which there is a scale of figures, h. Piv

The glass B is secured in a (No model.)

oted to the plate 3/ there is a weight or bar, Z, 5 which serves the double purpose of a connterbalancing weight and index finger.

In the use of my improvement the bar Z-is swung inwardly or outwardly on its pivot a distance corresponding with the number of minutes it is desired to have the glass run before giving an alarm. The arm I) is then turned up against the top 2, and when enough of the sand r has run out of the upper portion of the glass into the lower portion thereof to 5 transfer the center of gravity in the movable parts from above the center of motions (journals t) to below the same, the crate D will be suddenly reversed or partially rotated on its axis and the hammer it caused to strike the hell 0, and thereby give an alarm, indicating that the time has expired for which the glass was set.

I do not confine myself to the use of the bell O and hammer k, as these may be dis pensed with and a very effective device of this characterproduced by the other parts; neither do I confine myself to constructing the frame and crate, one or both, of wire, as any suitable materials may be employed and they may be made of any suitable form; nor to pivoting the bar Z, as it may be made adjustable in any other suitable manner.

It will be obvious that the arm b not only serves as a handle for the hammer or striker is, but as a stop to prevent the crate D and glass B from being tipped backwardly too far.

Having thus explained my invention, what I claim is In a device of the character described, the Sc body A, jonrnaled crate D, arm or stop I),

hammer k, arm S, plate y, adjustable bar Z, brace 11, and bell 0, combined and arranged to operate substantially as described.

SAMUEL SMITH.
